Motiviation: The current read loops don't fascilitate reading a maximum amount of bytes. This capability is useful to have more fine grain control over how much data is injested. Modifications: - Add a setMaxBytesPerRead(int) and getMaxBytesPerRead() to ChannelConfig - Add a setMaxBytesPerIndividualRead(int) and getMaxBytesPerIndividualRead to ChannelConfig - Add methods to RecvByteBufAllocator so that a pluggable scheme can be used to control the behavior of the read loop. - Modify read loop for all transport types to respect the new RecvByteBufAllocator API Result: The ability to control how many bytes are read for each read operation/loop, and a more extensible read loop.
